FOR SAFE OPERATION
<Electrical danger>
• During troubleshooting, checking the wiring, measuring voltage and electric current; be
careful to avoid electric shock.
• During maintenance, turn off the power unless it is required for maintenance.
<Mechanical danger>
• Be careful to avoid getting caught in rotation parts such as the gears, belts or rollers.
Familiarize yourself with the movements of these parts before using the equipment.
• It is possible that certain covers, moving parts, etc., may cause injury. Make sure to hold
covers, etc., securely during work.
<Important precautions>
• The machine is comprised of various parts, some of which are heavy. When moving or
removing such parts, be sure to hold these parts securely.
• When moving the machine, be sure that at least two persons work together.

[1] Checking the AC Adapter
DC Connector
1. Detach the plug of AC adapter from the AC
adapter inlet of the main unit.
Red Cable
2. Connect the wall socket plug of the AC adapter
to the wall socket.
Black Cable
3. Using a tester, measure the voltage at the plug
which will be connected to the main unit. (Fig. 1)
Fig. 1
● The AC adapter will be working fine, if the
voltage is minus (-) at the inner area and
plus (+) at the outer area of the connector
and also the meter reading is in the range
of 14V to 19V.
● When the measured voltage is 0V, or less
than 14V, the AC adapter will be defective.
Caution
EC-3700
Replace the AC adapter.
Never short-circuit the plug of AC
adapter. This will damage the AC
adapter.
If the AC adapter is working normally, the system
checks the items on the next page.

Illsutrations
[3] When the meter reading at step 2. is 0V or less
than 14V, check the main unit in accordance with
the following procedures:
Correct for 14V thru 19V
1. Remove the frame cover. (See sections D-1
and D-2 "Removing the Frame Covers.")
Power Supply Board
2. With the control unit removed, connect the AC
adapter, and turn on the power switch. Measure
the voltage across the electrolytic capacitor C1
on the power supply board (25V 1000µV).
(Fig. 4)
Caution
Black Cable
The layout of the power supply
board may be different from lot to
lot. (Figs. 5 and 6)
● The wiring within the frame is correct when
the measured voltage is in the range of 14V
to 19V. When the voltage across the
electrolytic capacitor on the power supply
board is correct, the 5P cable, which
connects the power supply board and the
control unit, may be defective.
Replace the 5P cable.
● When the measured voltage is 0V, the
wiring within the frame is defective.
Replace the Inlet Metal Base Set.
● When the problem cannot be remedied
even if the 5P cable is replaced, the power
supply board may be defective.
Replace the power supply board.

[2] Adjustment of Coil Current Value
Power Supply Board A
1. Connect the cables for measuring coil current
between the female connector of the solenoid
coil and the male connector (CN-1) on the
power supply board, and then connect the
cables to an ammeter. (Fig. 2)
2. Turn on the power switch of the main unit, set
the control unit to the manual mode, set the
load display to 4.0 kg•m, and start the system.
3. Adjust the potentiometer (as shown in Figs. 3
and 4) on the power supply board with a bladehead screwdriver so that the coil current will be
the value indicated on the workload unit
solenoid coil. (A clockwise turn will increase
the current, while a counter-clockwise turn will
reduce the current.)
Example: When the indication is 630 as shown
in Fig. 5, adjust the potentiometer
so that the coil current value will be
630mA.
4. Upon completion of the adjustment, detach the
cable for measuring coil current, and connect
the CN-1 connector directly to the power
supply board.

● Regarding the workload unit, positions of
copper disk plate and solenoid coil core slit
have been adjusted before mounting the
frame so that they will not touch each other
while the plate is rotating. However, due to
positional distortion caused by tightening
the bolts while the frame is being mounted,
the copper disk plate may touch the core.

■ Adjustment Method of Flywheel
Since the plain belt which delivers the rotation of both
the workload unit and flywheel requires an adequate
tension, a specified tension should be given to the
plain belt in the following adjustment procedures. For
this adjustment, a commonly available spring scale.
